One of the many potential projects that I’ve been thinking about, ever since I moved to WordPress, was to write a plug-in that would show past blog posts in a widget, just stuff that was posted on the current day, in past years. It seemed like it would be a good little project that I could use to learn more about programming for WordPress. Well, I never got around to writing it, and now I’ve found an existing plugin that does just what I wanted: On This Day. So I’ve added it to this blog. Since I’ve been blogging for more than ten years now, there’s almost always a few interesting things showing up in it.
